The AdderView Pro AV4PRO-DVI-QUAD-US is a professional grade KVMA switch delivering ultimate flexibility for users who wish to share a high resolution screen and modern USB peripherals between a multiplicity of computers.

The AdderView Multiscreen AV4PRO-DVI-QUAD is designed to enable four quad-head computers to be controlled from a single high resolution KVM console using either dual link DVI or high definition analogue video links. The switch makes use of Adder's True Emulation technology which enables USB HID devices to be continuously emulated to each computer. This unique technology enables instantaneous and reliable hotkey switching whilst also supporting the extra keys and features of enhanced keyboards and mice. Furthermore, the AdderView includes two independently switchable USB 2.0 channels and an audio channel, giving the user the flexibility to attach selected peripherals to different computers. Models are available supporting single, dual, triple or quad head DVI or VGA computers.

Adder AV4PRO-DVI-QUAD Features

Full Dual Link DVI-I video with extended profile DDC EDID

The AdderView Pro features full dual link DVI video delivering 4 megapixel resolutions at 60Hz. Because the AdderView features DVI-I, you can also use a mixture of digital and analogue sources without swapping cables. The extended DDC EDID profile ensures that the switched graphics card is always optimised to work with your screen. The dual link DVI capabilities enable users to work at very high resolutions including 2K (2048 x 1080) for film post production or WQXGA (2560 x 1600) for detailed medical imaging.

Broad USB 2.0 Hi Speed device support

A vast range of USB devices can be connected to the AdderView. From non standard human interface devices to printers and scanners. This gives great flexibility. For example, you could be scanning a set of documents onto one computer whilst working on another and printing from yet another, all at the same time. The USB 2.0 switching action has been carefully engineered to ensure maximum computer reliability when connecting and disconnecting USB devices.

Independant simultaneous device selection

Flexibility is key to the AdderView Pro AV4PRO-DVI-QUAD. The switch enables you to use the KVMA console to work on one computer whilst your USB peripherals are connected to other computers and your speakers are playing music from yet another. You can of course still switch all connected devices to any one of the connected computers as with any other KVM switch.

True emulation USB2.0 technology

The AV4PRO-DVI-QUAD belongs the first KVMA range of switches to feature Adder's advanced True USB Emulation technology. Emulated USB provides an instantaneous and reliable switching action and makes keyboard hotkey and mouse switching possible. However, previous implementations have used only generic emulations and consequently have only been able to support the most basic keyboard and mouse features. Adder's revolutionary True Emulation technology overcomes this frustrating limitation by emulating the true character of the connected devices to all the computers simultaneously. This means that you can now use the extra function keys, wheels, buttons and controls that are commonly found on modern keyboards and mice. With the AV4PRO-DVI-QUAD, a whole new group of users can take advantage of the flexibility KVM switches have to offer. Users in Architecture, Graphic design, Post production, Animation etc. often need to use specialised interface devices such as graphics tablets, 3D explorers, joysticks, and so on. The AV4PRO-DVI-QUAD makes all this possible using Adder's True Emulation technology.

Channel selection options

The AdderView Pro AV4PRO-DVI-QUAD can be switched using selectable keyboard hotkeys, 3 button mice or the front panel controls. Optionally, you can also use the RC4 remote switch to make your selection.These switching options allow you to rapidly reasign connected devices to any of the connected computers.

Options port for control, synchronisation and upgrade

An 'Options' port enables the AV4PRO-DVI-QUAD to be remotely switched using simple ASCII codes. When the channel is switched, the same ASCII codes are echoed to the 'Options' port and so, by linking 'Options' ports, two or more units can be switched in synchrony to create a multi video head switching system. The port enables a 4 button switch unit (RC4) to be used with the AV4PRO-DVI-QUAD. The same port can also be used to upgrade the firmware to guarantee that your hardware investment continues to deliver real value well into the future

Plug and Play

AdderView Pro KVM devices are delivered in a zero configuration state so you can plug them in and start working on them straight away. There is no need for drivers or software to be installed.

Question: We use dual Barco medical monitors each with 1640x2048 resolution. Does the AV4PRO-DVI-QUAD-US support this resolution?
Answer: The native resolution of the Coronis monitors is 3280 x 2048. If the monitors have two DVI connections per monitor, which I believe they do, than the resolution 1640 (half of 3280) x 2048 should work. If the monitors have a single DVI connection there is the possibility that the switch will only work in grey scale mode.

Other considerations include:
Our switches work with most, but not all, Barco calibration software versions. You may also need to enable hybrid DDC to turn on two-way DDC.

This is a very specific application, to ensure a compatible solution it may be best to discuss your specific requirements over the phone. We can calculate the required bandwidth needed and find the appropriate switch for your application. Give us a call at 1-877-586-6654 to discuss your project in more detail.

Question: Does this switch Support wireless mice/keyboards - Specifically Logitech Unifying recivers
Answer: Thank you for your inquiry.
We have not tried this switch with wireless keyboards or mice. In general, however, using wireless keyboards and mice is very hit or miss when it comes to KVMs. This is related to the very different way in which wireless peripherals communicate and a KVM's internal mouse/keyboard emulation. We cannot guarantee a particular wireless setup will work with a particular KVM.

That being said, customers who attempt to use wireless keyboards and mice find Avocent switches, like this model: http://www.kvm-switches-online.com/4sv120bnd1.html, to work best. Alternatively, we have heard of some success when using a KVM equipped with a USB hub in addition to the USB console connectors. However, this typically results in some loss of functionality in regards to Hotkey switching and other keyboard supported functions.

Again, it is a hit or miss proposition and we cannot guarantee any switch will work. For best performance and compatibility, we always suggest wired keyboards and mice.
